HELP PLEASE!! ASAP What would the mass be in kg?
Answer:
i guess answer is 0.0600
Explanation:
Here,
Density=0.791g/cm^3
Volume=75.89ml
So,
Mass=Density*Volume
=0.791g/cm^3×75.89ml
=60.02g/cm^3.ml
Expressing them in kg
60.02/1000
=0.0600 kg

What mass of water can be made from 24 grams of oxygen and 16 g of hydrogen?
H2 + O2 -> H2O
Answer:
27.025 g of H₂O
Explanation:
The Balance chemical equation is
2 H₂ + O₂ = 2 H₂O
Step 1: Calculate Limiting Reagent
Moles of H₂
Mole = 16 g / 2.02 g/mol = 7.937 mol
Moles of O₂
Mole = 24 g / 32.00 g/mol = 0.750 mol
Mole ratio of H₂ : O₂ is 2 : 1. Hence, 7.937 mol of H₂ will need 3.9685 mol of O₂. This means O₂ is limiting reagent.
Step 2: Calculate Moles of H₂O
0.750 mol of O₂ will produce 1.50 mol of H₂O because the mole ratio of O₂ : H₂O is 1 : 2.
Step 3: Calculate mass of H₂O
Mass = 1.50 mol × 18.02 g/mol = 27.025 g of H₂O

Explanation:
A chemist reacts sodium metal (Na) and chlorine gas (Cl) to form salt according to the balanced chemical equation: Na Cl → NaCl. If the chemist has 35. 0 g Na, what mass of chlorine must he or she use to react completely with the sodium? Finally, solve (remember significant figures):.
If the chemist has 35.0 g of Na, then 26.94 grams of chlorine is required to react completely with the sodium.
How we calculate number of moles?Number of moles of any substance can be calculated as [tex]${\rm{n = }}\frac{{\rm{W}}}{{\rm{M}}}$[/tex].
Where, W = given mass
M = molar mass
Balanced equation for the formation of NaCl can be written as:
[tex]${\rm{2N}}{{\rm{a}}_{{\rm{(s)}}}}{\rm{ + C}}{{\rm{l}}_{\rm{2}}}_{{\rm{(g)}}} \to {\rm{2NaC}}{{\rm{l}}_{{\rm{(s)}}}}$[/tex]
Here the ration of Na and Cl is 2:1.
No. of moles of Na = 35/23 = 1.52 mole
If 2 moles of Na is consumed by 1 mole of Cl, then 1 mole of Na is consumed by half mole of Cl.
Mole of Cl required to consume 1 mole of Na = 1.52/2 = 0.760 mole.
Now used mass of Cl can be find out by using the formula of moles as follow:
W = 35.45 × 0.760 = 26.94 grams
Hence, 26.94 grams of Cl is required to completely react with 35.0 grams of Na.

What do you already know about fossils? Describe as much as you can in the space below.
Answer:
Fossils are remains or traces from ancient life's that is most likely buried in rocks anywhere in the world. Fossils are basically bones, teeth, shells, nests, leaf impressions, and footprints. That is technically explaining what our planet was like long ago. Some dinosaur fossils have been found. Paleontologists find them almost everywhere. If you don't know what Paleontologists are, they're basically people who study fossils. A lot of fossils are found in sedimentary rocks. Sedimentary is a rock that has been formed from things like sand, mud, and many other kinds of rocks.

In a heat engine, 700 J of heat enters the system, and the piston does 400 J of work. What is the final internal (thermal) energy of the system if the initial energy is 1200 J? 300 J 900 J 1100 J 1500 J.
The first law of thermodynamics characterises the two types of energy transfer, as heat and as thermodynamic. The final internal (thermal) energy of the system is 1,500 J.
What is internal energy?The energy present in a system itself for conducting reactions is called internal energy.
Given,
Heat entering system (Q) = 700 JWork done by the piston (W) = 400Initial energy [tex](\rm U_{1})[/tex]= 1200 JAccording to the first law of thermodynamics:
[tex]\rm Q = \Delta U + W[/tex]
Substituting values in the above equation:
[tex]\begin{aligned}\rm Q &= \rm U_{2} - U_{1} + W\\\\\rm U_{2} &= \rm Q - W + U_{1}\\\\\rm U_{2} &= 700 - 400 + 1200\\\\&= 1500 \;\rm J\end{aligned}[/tex]
Therefore, option D. 1500 J is the final energy.

Answer:
Forest fire
Explanation:
Mark me as brainliest
Environmental change that is considered short term is forest fire.
What is short term environmental change?Short-term environmental change is the environmental change that occurs quickly and affects organisms. Forest fires are an example of a short- term environmental change.
Short-term changes include changes in seasonal patterns, unseasonal rainfall, changes in the life cycle of insects and animals, and so on. Long term changes examples are melting of glaciers or a rise in levels of water bodies which may cover islands close to sea level.
El Niño and La Niña are two examples of short-term climate changes lasting one to a few years. In an El Niño, the trade winds reverse direction, as do the equatorial surface currents. This causes warm water to pool off of South America and stop upwelling. A La Niña is like normal conditions only more so.
Therefore, Environmental change that is considered short term is forest fire.

Calculate the heat energy required to melt 4kg of ice when the specific latent heat of fusion of water is 334,000 J/kg.
1336 kJ
2336 kJ
3336 kJ
HELP ASAP
[tex]\bold{\huge{\blue{\underline{ Solution}}}}[/tex]
We have given in the question that,
4kg of ice melts at the specific latent heat of fusion of water is 334,000 J/kg .We know that,
Amount of heat required = Mass * specific heat * change in temperature
[ Specific Latent heat of fusion is the amount of heat required to change one mole of substance from solid to liquid phase without changing in temperature .]
But, For complete melting of substance without change in temperature
Amount of heat required = Mass * Specific latent heat of fusion
Subsitute the required values,
[tex]\sf{\red{ Q = MCl}}[/tex]
Where,
Q = Amount of heat required M = Mass of the substance Cl = Specific latent heatNow,
[tex]\sf{ Q = 4 × 334000}[/tex]
[tex]\sf{ Q = 1336000 J }[/tex]
[tex]\sf{ Q = 1336 KJ }[/tex]
Hence, The amount of heat required to melt 4kg ice is 1336KJ
[tex]\bold{\red{ Option\: A \:is\: correct }}[/tex]
Taking into account the definition of calorimetry and latent heat, the heat energy required to melt 4 kg of ice when the specific latent heat of fusion of water is 334,000 [tex]\frac{J}{kg}[/tex] is 1,336 kJ.
CalorimetryCalorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Latent heatLatent heat is defined as the energy required by a quantity of substance to change state.
When this change consists of changing from a solid to a liquid phase, it is called heat of fusion and when the change occurs from a liquid to a gaseous state, it is called heat of vaporization.
The heat Q that is necessary to provide for a mass m of a certain substance to change phase is equal to
Q = m×L
where L is called the latent heat of the substance and depends on the type of phase change.
Heat energy required to melt iceIn this case, you know:
m= 4 kgL= specific latent heat of fusion of water= 334,000 [tex]\frac{J}{kg}[/tex]Replacing in the expression for latent heat:
Q = 4 kg× 334,000 [tex]\frac{J}{kg}[/tex]
Solving:
Q= 1,336,000 J= 1,336 kJ (being 1,000 J= 1 kJ)
Finally, the correct answer is the first option: the heat energy required to melt 4 kg of ice when the specific latent heat of fusion of water is 334,000 [tex]\frac{J}{kg}[/tex] is 1,336 kJ.
